The Basics RNA Isolation. Obtaining high-quality RNA is the first, and often the most critical, step in performing many molecular techniques such as reverse transcription real-time PCR RT-qPCR, transcriptome analysis using next-generation sequencing, array analysis, digital PCR, northern analysis, and cDNA library construction.
Whilst separation techniques relying on gravitational forces have become relatively sophisticated in their application to biology the same is not true for magnetic separation procedures. The use of the latter has been limited to the few cells which contain paramagnetic iron. However with the develop
The magnetic separator consists of a large electromagnet through which mineral mixtures can be passed on a metal trough which is divided near its exit end. Varying the strength of the magnetic field andor slope of the separation trough is used to separate minerals. All forms of mineral separation

Column-free magnetic cell separation techniques involve placing a tube filled with a magnetically-labeled sample within a magnetic field. The magnetically-labeled target cells will migrate towards the magnet and will be immobilized at the sides of the tube. The unlabeled cells in suspension can then be poured or pipetted off to separate them ...
